Compact DIP Switch For Smart Doorbell Devices

A low-profile, miniature DIP switch designed for code-setting and configuration in smart doorbell transmitters, receivers, and chime modules. Optimized for tight enclosures, the switch delivers reliable, low-level signal routing with clear tactile feedback and long service life. Available in SMT and through-hole variants and multiple position counts to match different pairing and feature set needs.

Key Features

• Compact footprint and low height for slim doorbell housings
• 2.54 mm pitch with 4, 6, 8, 10, or 12 switch positions
• Clear ON marking with recessed actuator to prevent accidental toggling
• Gold-over-nickel contacts for stable, low-level signal switching
• Matte-tin terminal plating for robust solderability (lead-free)
• SMT (gull wing) and THT (straight pin) options
• Optional washable seal for post-solder cleaning
• RoHS and REACH compliant; halogen-free materials
• Housing material rated UL94 V-0 for flame retardancy

Typical Applications
